Consider a binary choice model in random utility framework: U1 = Bo + B1x1 + · ·. + BrXk + u = x'B+u and Uo = 0, where Uj and Uo are utilities from y = 1 and y = 0. When u follows the standard logistic distribution [the CDF of u is A(u) 1+e« ], what is the partial effect from a1 on the choice probability of choosing 1? B1 A(x'B)B1 A(x'B)[1 – A(x'B)]B1
